I should preface this review with an admission that I did not purchase these drapes for the usual purpose, which is to block sunlight. I didn't buy these for a window at all, but to block the light from a sink vanity.My husband and I bought a house that was built in the 80s, and it seems to me that 80s contractors believed "open concept" was a great idea in the main bedroom and en suite. For some reason, the vanity and sink for the en suite bathroom is in the middle of the closet and the room with the toilet and shower/tub. My husband gets up at 5:45 AM because he's a masochist, and I prefer to wake up naturally with the sun. But when he gets up to get ready, he turns on the vanity light which lights up the room and wakes me up. I'm not particularly please to be awake before the sun, it's not natural.As a short term solution, I took some light diffusing voiles and hung them from a tension rod across the opening. Aside from disguising the sight of the vanity itself, they didn't help with the light. So I bought these drapes at 96" in the lovely green. It says olive, I say these are too dark for olive, but as I have varying shades of green in the main bedroom, it isn't an issue.plus I love the color.The were initially a little shorter than my existing voiles, but that was due to being severely wrinkled from packaging. After I took my hand held travel steamer to them, the feel straight. They hang at the correct length post steam, and when my husband pulls them together in the morning, they do effectively block the light from the vanity.However, I did notice that when I was on the other side and the sun was filtering through the window in the bedroom that the sunlight DID show through the fabric from the other way. I don't know if these would be 100% effective at blocking sunlight to a blackout effect. I'm rating them 5 stars because: they are pretty, the fabric is soft, they were much heavier than I anticipated for the price, the color is lovely, and they have performed the office for which they were intended beautifully.
